Simplify The Expression: $\frac{2y}{y^2 + 6y}$

$$

Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it is essential to understand the techniques involved in simplifying expressions. In this article, we will focus on simplifying the expression $\frac{2y}{y^2 + 6y}$. We will use various techniques such as factoring, canceling, and combining like terms to simplify the expression.

Understanding the Expression

The given expression is $\frac{2y}{y^2 + 6y}$. This expression consists of a numerator and a denominator. The numerator is $2y$, and the denominator is $y^2 + 6y$. To simplify this expression, we need to analyze the denominator and see if it can be factored.

Factoring the Denominator

The denominator $y^2 + 6y$ can be factored by taking out the common factor $y$. This gives us $y(y + 6)$. Now, we can rewrite the original expression as $\frac{2y}{y(y + 6)}$.

Canceling Common Factors

Now that we have factored the denominator, we can see that there is a common factor of $y$ in both the numerator and the denominator. We can cancel out this common factor by dividing both the numerator and the denominator by $y$. This gives us $\frac{2}{y + 6}$.

Simplifying the Expression

We have now simplified the expression $\frac{2y}{y^2 + 6y}$ to $\frac{2}{y + 6}$. This is the simplest form of the expression.

Conclusion

In this article, we have simplified the expression $\frac{2y}{y^2 + 6y}$ using various techniques such as factoring, canceling, and combining like terms. We have shown that the expression can be simplified to $\frac{2}{y + 6}$. This is an essential skill in mathematics, and it is crucial to understand the techniques involved in simplifying expressions.
